Asset Allocation, R26

Can anyone explain the Resampled Efficient Frontier, in plain English? Basically it’s the MVO re-run several times, to dampen sensitivity to the input estimates? Also, my recollection from last year is that it’s important to know the advantages and disadvantages of this + Black/Litterman + Monte Carlo simulation approaches? Thanks p.s. jumping ahead… example 17 on pages 309-11… seems like answer iv. is a screw-up? haven’t checked the errata yet

sorry… this is CFAI books, V3
